traction control
Hey newbie here just bought a 1999 with 6 speed.When I corner the vehicle agressive but not to the point of losing traction it cuts back power to nothing.The display says traction control active.It started doing the same driving straight with just mild acceleration? It cuts power all way out when i switch traction control off it rests? Any ideas?Thanks

The traction control system will activate if the rear wheels are found to be spinning faster than the front wheels. Obviously - if you lose traction on the rear wheels on either a slippery surface, or you apply too much throttle to cause wheel spin, the traction control system will activate.
But if the rear tires are either equal or shorter than the front tires, the system will detect the rear wheels spinning faster than the fronts and will activate T/C.
This is how the T/C system works - it compares the rate of spin front vs. back, and if the back is spinning faster than the front it will apply brake to the faster spinning wheels.

The 285-20x20 in back is 24.49 overall diameter and the 245-35x20 in the front is 26.75 overall diameter, meaning the back tires are almost 1.75" shorter than the front.
That's your problem. You need a taller tire in back than the front. The only way around this is to change the tires.

Whoever put those wheels/tires on F'd up. Better off selling them and getting some proper sized wheels. Depending on your budget you can get the stock 17/18 or 19/20 combo. The tires are what geeked up the offset though... theres a couple guys on here running 20/20.

Jake is right - I'd sell the wheels, or at least the fronts if you can find a 19" front, get the proper sized tires and you should be good to go. If you want to PM me for help, feel free to do so. I can help you choose the right sized tires if the whole thing confuses you.

replaced plugs and wires cleaned the grounds.I am not throwing codes and am driving with traction control in regular mode! No more issues under hard cornering or acceleration. The tires were not the problem.Works fine with 20s front and rear.
